Application YNovember 12, 1946, Serial No. 709,3 67 6 claims. (cl. 1st-37) My invention relates to a model airplane rotating stand and the objects of my invention are:

First, to provide a rotating stand of this class having novel motivating means for operating model airplanes in connection therewith;

Second, to provide a novel mechanism for operating various mechanical toys;

Third, to provide a model airplane rotating stand of this class which may be constantly wound while in operation;

Fourth, to provide a model airplane rotating stand of this class in which the operating mechanism thereof, is very easily and simply wound by small children;

Fifth, to provide a. model airplane rotating stand of this class which is very simple to maintain and repair;

Sixth, to provide a model airplane rotating stand of this class in which the actuating mechanism, thereof, may be entirely wound by one single movement of the winding lever, thereof; and

Seventh, to provide a model airplane rotating stand of this class which is very simple and economical of construction, efficient in operation, and which will not readily deteriorate or get out of order.

With these and other objects in View, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, forming a part of this application in which:

Figure l is a side elevational View of my model airplane rotating stand showing portions broken away and in section to amplify the illustration; Fig. 2 is an enlarged plan sectional view taken from the line 2 2 of Fig. 1; and Fig. 3 is a fragmentary bottom plan view of my model airplane rotating stand vshowing portion, thereof, broken away and in section to amplify the illustration.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The base I, shafts 2 and 3, gears 4 and 5, rollers S and l, resilient band 8, axle 9, bolt I0, ratchet wheel II, pawl I2, spring I3, cross arms Ill, airplane I5 and operating handle I 6 constitute the principal parts and portions of my model airplane rotating stand. The base I of my model airplane rotating stand is a substantially box-like structure arranged in inverted position, wherein, the open side thereof, rests on the oor or any other suitable surface during operation. This base I is provided with a centrally disposed upwardly extending hollow cylindrical sleeve la in which the hollow shaft 2 is revolubly mounted as shown best in Fig. l of the drawing. This hollow shaft 2 is provided with a bore portion 2a therein, arranged to contain the shaft 3 which is freely and revolubly mounted, therein. Fixed on the shaft 3 is the ratchet wheel II engaged by the pawl I2 maintained in engagement with the ratchet wheel Ii by the spring I3, all as shown best in Figs. l and '2 of the drawings. The upper end of the shaft 2 is provided with a plate-2b on which the pawl I2 and spring I3 are mounted. Secured in connection with the lower end of the shaft 2 is the pinion gear 4 meshing with the gear 5 of considerably larger diameter. This gear 5 is secured to the shaft Ia of the operating handle I6 which projects through the top side Ib of the base I. This shaft Ita is provided with an enlarged hub Ibbearing in the upper side portion Ib of the base I supporting the gear 5 together with the roller 6 in the base I, all as shown-best in Fig. 1 of the drawing. The roller 1 as shown in Fig. 3 of the drawings is fixed to the base I by means of the axle S which is secured at its upper end to the frame plate Ic below the upper side Ib of the base I. The bolt I8 is also secured to the frame plate Ic and supports one end of the resilient band 3 which passes over the roller I and is secured at its opposite end in connection with the roller 6 as shown in Fig. 3

' of the drawing. This resilient band 8 is an endless member looped over the bolt I0 at one folded end, thereof, and looped over a pin 6a extending through an arcuate recess 6h in the roller 6 in.- wardly of the drum surface 6C, thereof, al1 as shown best in Fig. 3 of the drawing. At the transition of the slotted portion 6d in the roller 6 communicating with the arcuate recess portion 6b in the drum surface 6c, the band 8 passes around the drum surface 6c on which it is wound.

It will be here noted that the roller 1 is revolubly mounted .on the axle 9 and that the operating handle I6 together with the shaft IEa. secured to the gear 5 and roller Ii are all rigidly secured together. Secured to the normally upper end of the shaft 3 are the cross arms I4 having open loop portions Illa at their outer ends from which the links I5a are suspended for supporting the airplanes I5, all as shown best in Fig. l of the drawing. f

The operation of my model airplane rotating stand is substantially as follows:

When the handle IB is forced in the direction as indicated by the arrow A in Fig. 3 of the drawing, the roller 6 is rotated in connection with the shaft IBa secured to the handle IB winding the resilient band 8 around the periphery of the roller 6 which is preliminarily stretched over the roller l creating tension in said resilient band before it is wound upon the roller 6. When the operating handle I6 is released, tension in the resilient band 8 tends to force the operating handle I6 together with the roller 6 in the opposite direction from the arrow A as indicated in Fig. 3 of the drawing, whereupon the gear 5 in mesh with the pinion 4 rotates the pinion 4 at a considerably greater speed causing rotation of the shaft 2 with which the pawl i2 is connected. This pawl l2 engages a tooth of the ratchet wheel Il causing synchronous rotation of the shaft 3 relatively to the shaft 2. When the operating handle IE comes to rest adjacent the sleeve la f the base l, the shaft 3 continues to rotate due to inertia of the airplane l in connection with the links I5a whereby teeth of the ratchet wheel Il pass the pawl l2 permitting the operator to again operate the handle I6 winding the resilient member 8 on the roller 6, whereupon the ratchet wheel` ll is again engaged by the pawl l2 for continued acceleration of the shaft 3 together with the cross arms t4 and airplane in connection therewith. It being noted that the teeth Haare provided with inclined surfaces in one direction and positive abutment portions facing the opposite direction whereby the pawl l2 is engageable with the ratchet wheel fi when operating in one direction only. If desired the operating handle I6 may be moved each time the resilient band 8 is unwound until the rotation of the shaft 3 is considerably accelerated due to the remaining speed of rotation after each complete unwinding movement of the operating handle i6 together with the roller 6.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention, the construction, combination and arrangement, substantially as set forth in the appended claims.
